Storage requirements

Before you install IBM® Cloud Pak for Data, review the storage requirements for the control plane, the shared cluster components, and the services that you plan to install.

Cloud Pak for Data platform storage requirements

A Cloud Pak for Data deployment requires several types of storage:

Storage for images in the private container registry
Depending on your environment, you might need to store images in a private container registry rather than pulling them directly from the IBM Entitled Registry.

If you use a private container registry, you must have sufficient space for the Cloud Pak for Data components that you plan to install.

Sizing
A minimum of 300 GB of storage space in the private container registry.
Tip: You can use the cpd-cli manage delete-images command to remove unused images from the private container registry.
Local storage for container images
Each node on your cluster must have local storage for the container images that are running on that node.
Storage location
The container images are stored in the root file system on the nodes.

On Red Hat® OpenShift® Container Platform, local copies of the images are stored in /var/lib/containers.

Sizing
A minimum of 300 GB of storage space per node.
Persistent storage
Cloud Pak for Data supports and is optimized for several types of persistent storage:
Storage option Version Notes
OpenShift Data Foundation (formerly called OpenShift Container Storage) Version: 4.6 or later Available in the IBM Storage Suite for IBM Cloud® Paks

Ensure that you install a version of OpenShift Data Foundation that is compatible with the version of Red Hat OpenShift Container Platform that you are running. For details, see https://access.redhat.com/articles/4731161.
IBM Spectrum® Fusion Version 2.4.0 or later fixes Available in either:
  • IBM Spectrum Fusion
  • IBM Storage Suite for IBM Cloud Paks
IBM Spectrum Scale Container Native (with IBM Spectrum Scale Container Storage Interface) Version 5.1.3.x or later fixes

CSI Version 2.5.x or later fixes

 Available in either:
  • IBM Spectrum Fusion
  • IBM Storage Suite for IBM Cloud Paks
Portworx Version 2.9.1 or later fixes  
NFS Version 3 or 4

The latest version is recommend.

  
Amazon Elastic Block Store (EBS) Not applicable Your environment must also include EFS storage.
Amazon Elastic File System (EFS) Not applicable It is recommended that you use both EBS and EFS storage.
IBM Cloud Block Storage Not applicable Your environment must also include IBM Cloud File Storage.
IBM Cloud File Storage Not applicable It is recommended that you use both IBM Cloud Block Storage and IBM Cloud File Storage storage.
When you plan your environment, ensure that you review the storage types that are supported by the components that you plan to install:
Tip: The preceding storage options have been evaluated by IBM. You can run the Cloud Pak for Data storage validation tool to assess storage that is provided by other vendors. However, this tool does not guarantee support for other types of storage. You can use other storage environments at your own risk.
Sizing
The minimum amount of storage depends on the type of storage that you plan to use. For details, see the Resource requirements section under Storage comparison.

As a general rule, Cloud Pak for Data with all services installed can use up to 700 GB of storage space. Review the Storage comparison to ensure that you have sufficient storage space available for user data based on the type of storage that you select. You can add additional capacity depending on your user data volume requirements.

Cloud Pak for Data control plane persistent storage requirements

The Cloud Pak for Data control plane supports all of the persistent storage options that are supported by the platform. When you install the control plane you must specify a block storage class and a file storage class for your environment.

The following table lists the recommended block storage classes and file storage classes for each type of storage. If you use different storage class names on your cluster, ensure that you specify equivalent storage classes.
  • Block storage supports ReadWriteOnce (RWO) access
  • File storage supports ReadWriteMany (RWX) access
Storage option Recommended block storage class Recommended file storage class Notes
OpenShift Data Foundation ocs-storagecluster-ceph-rbd ocs-storagecluster-cephfs The default storage class names are different if you use external mode.
IBM Spectrum Fusion ibm-spectrum-scale-sc ibm-spectrum-scale-sc IBM Spectrum Fusion supports both ReadWriteMany (RWX access) and ReadWriteOnce (RWO access) with the same storage class. Specify the same storage class for block storage and file storage.
IBM Spectrum Scale Container Native ibm-spectrum-scale-sc ibm-spectrum-scale-sc IBM Spectrum Scale Container Native supports both ReadWriteMany (RWX access) and ReadWriteOnce (RWO access) with the same storage class. Specify the same storage class for block storage and file storage.
Portworx portworx-metastoredb-sc portworx-rwx-gp3-sc For more information about the recommended Portworx storage classes, see Creating Portworx storage classes.
NFS managed-nfs-storage managed-nfs-storage NFS supports only ReadWriteMany (RWX access). You must specify the same storage class for block storage and file storage.
Amazon Elastic Block Store gp2-csi or gp3-csi Not applicable. Your environment must include Amazon Elastic File System storage.
Amazon Elastic File System Not applicable. efs-nfs-client It is recommended that you use both Amazon Elastic Block Store storage and Amazon Elastic File System storage to ensure that you can install services that require block storage, but the Cloud Pak for Data control plane can function with only file storage.

If you use only Amazon Elastic File System, specify efs-nfs-client for both file and block storage.
IBM Cloud Block Storage ibmc-block-gold Not applicable. Your environment must include IBM Cloud File Storage.
IBM Cloud File Storage Not applicable. ibmc-file-gold-gid or ibm-file-custom-gold-gid It is recommended that you use both IBM Cloud Block Storage and IBM Cloud File Storage to ensure that you can install services that require block storage, but the Cloud Pak for Data control plane can function with only file storage.

If you use only IBM Cloud File Storage, specify the appropriate storage class for both file and block storage.

Shared component persistent storage requirements

The following table indicates the type of storage that each component supports. For information about the recommended storage classes for each component, see Recommended storage classes for the shared components.

  • File req indicates that a service can use the specified block storage only if file storage is also provided.
